Abstract: productivity is low due to use of poor quality seeds, inappropriate seed rate and unavailability of adaptable improved varieties to wide range of agro-ecologies. Therefore, this experiment was conducted at Kersa, eastern Ethiopia with the objectives of evaluating the effect of seeds sources, seed rates and varieties on yield and yield related traits and to determine seed quality of different sources of bread wheat varieties. The laboratory experiment was laid out as Completely Rand...
Abstract: A study was conducted using 40 yearling Arsi-Bale sheep with initial body weight of 19.85+0.29 kg (mean + SD). The objectives were to evaluate the varietal differences among faba bean straws and to evaluate effects of feeding different varieties of faba bean straws with concentrate (2 parts wheat bran: 1 part noug seed cake) fed at the rate 70% straws and 30% concentrate mixture on feed intake, digestibility, body weight gain and carcass characteristics of the animals. The varietie...
Abstract: Common bean (Phaseolus vulgaris L.) is an important food security crop in Ethiopia. However, the national average yield is very low owing to a number of abiotic and biotic stresses. Low soil fertility, coupled with limited fertilizer application practice by famers could be amongst the major one of the stresses that may caused for the low national mean yield of the crop in the country. Therefore, a field experiment was conducted at Bako to study the effect of integrated use of Rhizo...
Abstract: The experiment was conducted at Haramaya University Beef fattening station, to evaluate the effect of maize silage inclusion at different levels on feed intake, growth performance, carcass characteristics, and meat quality. Twelve castrated Harar oxen of average age 6 years with the initial body weight of 229±1.18 kg (mean+SE) were used for the experiment. The animals were randomly distributed to four treatments each with three replications in a completely randomized design. The d...
Abstract: This study was conducted to evaluate the growth performance, carcass characteristics, meat yield, primal meat cuts, meat quality, and some biochemical bases for tenderness of meat from bulls of Arsi, Harar, Jersey*Horro crossbred, and Ogaden cattle breeds finished on corn silage based diet at Beef Cattle Farm, Haramaya University, Ethiopia. A total of 12 bulls of four cattle breeds (i.e. 3 bulls from each breed of Arsi, Harar, Jersey*Horro crossbred, and Ogaden) with 2.0 to 2.5 yea...
Abstract: Movement restrictions introduced by the coronavirus pandemic have incentivized the rollout of online services globally. Additionally, more employees were telecommuting throughout the pandemic and remote work has become the new normal. This has provided nefarious actors with lucrative opportunities. Hence there has been an increase in online criminal and terrorism activities. The weaponization of the cyberspace is also a concerning trend in the ongoing geopolitical tensions. This is...
This research delves into the innovative application of feed-forward neural networks (FNNs) specifically the multi-layer perceptron (MLP). MLP is a flexible algorithm due to its ability to adapt to different realworld problems amongst other features, and this makes it a preferred machine learning algorithm in the early detection of mental health disorders. MLP’s number of layers and the number of neurons per layer changes to accommodate these abilities. MLP was chosen for this work becau...
Abstract: Smart societies have an increasing demand for quality-oriented services and infrastructure in an industrial Internet of Things (IIoT) paradigm. Smart urbanization faces numerous challenges. Among them, secured energy demand-side management (DSM) is of particular concern. The IIoT renders the industrial systems to malware, cyberattacks, and other security risks. The IIoT with the amalgamation of big data analytics can provide ef cient solutions to such challenges. This paper propose...
Abstract: Beneficiation of chalcopyrite and most minerals in general requires specific conditions and raw materials based on characteristics of the mineral to optimize processing hence income. Therefore characterization of minerals is an important aspect in mineral processing. In this investigation X-ray diffraction (XRD) and Scanning Electronic Microscope (SEM) techniques where applied on a sample of chalcopyrite. XRD was mainly applied to obtain phase compositions, lattice parameters hence...
Abstract: New generalized distributions namely Topp-Leone-G Power Series class of distributions, Marshall-Olkin-Exponentiated Odd Exponential Half Logistic-G family of distributions, Exponentiated Odd Exponential Half Logistic-G Power Series class of distributions and Marshall-Olkin-Type II-Topp-Leone-G family of distributions are presented. Properties of these generalized distributions including series expansion of density functions, hazard functions, quantile functions, moments, conditiona...
Abstract: Studies have linked herbal teas to the prevention of many diseases, leading to an increase in their use and demand which has endorsed an increase in their commercial activity and production. Consequently, performing a quality assessment of herbal teas in Botswana to determine their safety, medicinal and economical value has become of greater importance. The quality assessment tools used in this study entail: Antioxidant activity profiling using 2,2- diphenyl-1-picrylhydrazyl (D...
Abstract: Mixture models have gained popularity in statistical analyses because of their flexibility in cap turing local variations in heterogeneous populations. Model based approaches to classification use mixture models to fit data via maximum likelihood based approaches and provide labels to unlabelled observations. Over the years model based approaches have grown into an important sub-field of classification because they provide the uncertainty of classifying the unlabelled observations ...
Abstract: Network downtime is the period in which a computer system is unavailable or system fails to provide/perform its primary functions. System reliability and/or availability are very Key as an unavailable system is a failing system. It is very common is Botswana for government clients to forfeit being serviced because the government department system is down. The primary aim of this project was to investigate the causes of system/network downtimes in Botswana government department. Thr...
Abstract: In this article factors that affect the comminution behavior of heterogeneous diorite rocks obtained from two quarry locations in Botswana were investigated. Diorite rocks are in great abundance in Botswana and they are increasingly viewed as a relatively inexpensive and reliable alternative construction material to sustain the infrastructure growth in Botswana. The diorite rock samples collected from both the Central and North-Eastern districts were studied for structural similari...
Abstract: Technological advances for low-cost Wi-Fi applications such as ‘the wireless sensor network (WSN) deployment’ are at an advanced stage of acceptance, especially in smart home environments. The application of this kind of network is referred to as a wireless sensor home network (WSHN). In literature, the evaluation of customers' home wireless network performance level is usually done via real-time experiment or by experience to test the network’s performance, leading to networ...
